Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual cleaning methods are used for high-rise building windows, then cleaning can be performed, but safety risks increase and cleaning efficiency decreases
Solution Approach 1:
The cleaning system is divided into two separate cleaning units (first cleaning unit on inner surface, second cleaning unit on outer surface) that operate independently but are magnetically coupled. This segmentation allows each unit to be optimized for its specific surface while maintaining coordinated operation, improving both safety and efficiency.
Solution Approach 2:
The patent replaces traditional mechanical rope-based suspension systems with a magnetic field-based coupling system. The magnetic modules create a field-based connection between the two cleaning units, eliminating the need for complex mechanical safety systems and reducing safety risks while improving operational efficiency.
2Stability of the object's composition
If magnetic force is increased to improve attachment stability, then cleaning units remain firmly attached, but movement control becomes difficult
Solution Approach 1:
The magnetic force is made dynamic and adjustable rather than fixed. The magnetic modules can vary their magnetic field strength to provide strong attachment when needed and reduced resistance during movement, allowing the system to adapt between stability and mobility requirements.
Solution Approach 2:
The magnetic force parameter is changed and controlled to different levels based on operational requirements. The system can adjust magnetic field strength to optimize between firm attachment for stability and reduced magnetic resistance for easier movement control.
3Reliability
If magnetic modules are added to both cleaning units, then attachment reliability improves, but device complexity increases
Solution Approach 1:
The magnetic modules in the first and second cleaning units are designed to work together as an integrated magnetic coupling system. By merging the magnetic functions of both units, the patent achieves enhanced attachment reliability while avoiding the complexity of separate independent attachment systems.
